Class FlowBuilder.SplitBuilder<Q>

public static class FlowBuilder.SplitBuilder<Q>
extends java.lang.Object

A builder for building a split state. Example (builder is a FlowBuilder):

 Flow splitFlow = builder.start(flow1).split(new SyncTaskExecutor()).add(flow2).build();
 

where flow1 and flow2 will be executed (one after the other because of the task executor that was added). Another example

 Flow splitFlow = builder.start(step1).split(new SimpleAsyncTaskExecutor()).add(flow).build();
 

In this example, a flow consisting of step1 will be executed in parallel with flow. Note: Adding a split to a chain of states is not supported. For example, the following configuration is not supported. Instead, the configuration would need to create a flow3 that was the split flow and assemble them separately.

 // instead of this
 Flow complexFlow = new FlowBuilder<SimpleFlow>("ComplexParallelFlow")
                       .start(flow1)
                       .next(flow2)
                       .split(new SimpleAsyncTaskExecutor())
                       .add(flow3, flow4)
                       .build();

 // do this
 Flow splitFlow = new FlowBuilder<SimpleFlow>("parallelFlow")
                       .start(flow3)
                       .split(new SimpleAsyncTaskExecutor())
                       .add(flow4).build();

 Flow complexFlow = new FlowBuilder<SimpleFlow>("ComplexParallelFlow")
                       .start(flow1)
                       .next(flow2)
                       .next(splitFlow)
                       .build();
